SAFETY RAZOR BLADE SHARPENER Filed July 11, 1931 Patented Sept. 27, 1932 UNITED STATES PATENT OFFICE ELMER V. KLINE, OI UNIVERSITY CITY, MISSOURI, ASSIGNOR T0 VICTOR PHARMACAL COMPANY, INC., 01 ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI SAFETY RAZOR BLADE SHABPENER Application filed July 11,

1 upon a su port and held stationary by one hand, an having a curved wall against which a safety razor blade may be pressed and bent and operated in order to sharpen the opposite edges of the blade, and also having a portion adapted to be engaged by the thumb of the hand that manipulates the razor blade in order to steady and prevent the hand from slipping and to enable the operator to manipulate the razor blade along and against the curved wall with approximately a uniform and desired pressure.

Other objects of the invention will be made apparent by the following description, reference being made to the annexed drawing, 1n

5 which- Fig. 1 is a ers ective view of one formof my improve sa ety razor blade sharpener.

Fig. 2 is a vertical sectional view showing clearly the construction and arrangement of the curved wall by and against wh ch the razor bladeis sharpened, and also showin the construction engaged by the thumb of the hand that manipulates the blade in order to enable the operator to control the manipulation of the blade more effectively.

Fig. 3 is a perspective view of the device clearly showing the relationship of the thumb engaging portion with respect to the curved wall.

In the embodiment of the invention shown, my improved safety razor blade sharpener comprises a body formed with an end 1, a wall 2 opposite from the end 1, a pair of side walls 3 and 4 integrally connecting the end 1 with the end wall 2, a side wall 5 having its ends integrally connected with the end 1 and the end wall 2, respectively, and its side edges merging to integral connection with the walls 3 and 4, respectively. The wall 6 that is opposite from the wall 5 is curved 1931. Serial No. 550,087.

curvature, and has its upper and lower ends integrally united with the upper end 1 and the lower wall 2,.res ctively, and its side edges integrally unite and merging with the walls 3 and 4, respectively. Thus, the body is substantially rectangular with the exception of the curved wall 6 against and along which a safety razor blade is curved and bent along lines parallel with the longitudinal axis and with the side edges of said blade on approximately the same radius of curvature as the radius of curvature of the wall 6. Oscillation and manipulation ofthe razor blade thus held against the wall 6 will sharpen the opposite side edges of the blade because the surface of the said wall 6 is constructed and designed for that purpose.

The entire body of the device may be mad of glass. If desired, the body may be hollow so as to sired substance.

The end wall 2 is formed with a central concaved portion 7, thus producing on the outer side of said wall 2 a concavity 8 constructed and arranged to receive comfortably the ball of the thumb of that hand of the operator used to bend and manipulate the razor blade against and along the wall 6. Thus, the concavity 8 will prevent the thumb from slipping and will also function as a rest for the thumb so that the operator may apply approximately uniform and continuous pressure against the razor blade and thereby press the razor blade with approximately uniform and continuous pressure against the wall 6. The concavity 8 also functions as a fulcrum or pivot for the thumb so as to facilitate the manipulation of the fingers engaging the razor blade. The device 8 is a genuine convenience in this regard, as it performs satisfactorily the several functions indicated, irrespective of whether the device is supported in the hand provide a container for any deor is placed upon a support when being used such that the device may be easily laid upon a support and-may be held substantiall stationary on said support without possi ility of rocking or oscillating while the razor blade 9 is being manipulated and sharpened. The walls 3 and 4 are of sufiicient width to permit the device to be held on a support in the manner stated without dan r of cutting the fingers of the hand holding the device while the razor blade is being sharpened.

As indicated, the device may be made in the form of a container. In such case, the end 1 is formed with an opening 9 surrounded by a projecting neck 10, through which the 55 contents of the container may be discharged. The neck 10 may be closed by any suitable closure, as by-a cap 11 screwed into engagement with a thread 12 on the outer side of the neck 10.

' It is now clear that my invention may be manufactured inexpensively and is a genuine convenience for use in sharpening safety razor blades. The device may be held and manipulated more conveniently than any device for this purpose with which I am familiar, and these advantages are obtained as aresult of the novel construction shown and described.

I claim 1. A safety razor blade sharpener com rising a body of generally rectangular s ape having one flat wall and the opposite wall curving on uniform radius of curvature from said .flat wall and having in one end wall a concavity arranged to receive and substantially fit the ball of the thumb of the operator when the operator presses and manipulates a safety razor blade against said curved wall, and an engageable projection in connection with the end of said body opposite from said concavity.

2. A safety razor blade sharpener comprising a body having a curved wall along one side thereof bowing inwardly toward the opposite wall and having side walls constitutin a handle for holding and supporting sai body and having in one end wall a cavity arranged to receive and retain the thumb of that hand used by the operator to press and manipulate a safety razor blade against said curved wall.
